Description

Technical Field

[0001] This utility model relates to the field of screw fastening equipment technology, and in particular to a PCBA and bottom shell fastening equipment. Background Technology

[0002] Currently, in the assembly process of existing vehicle infotainment systems (vehicle computers), after the PCBA and the base are assembled, the PCBA and the base need to be screwed together. However, in existing assembly lines, the screwing process of PCBA and base takes a long time, while the assembly process of PCBA and base takes less time. Therefore, existing assembly lines are prone to material blockage during the PCBA and base screwing process, which leads to a decrease in the production efficiency of the assembly line. Utility Model Content

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a PCBA and bottom shell locking device to solve the problem that material blockage easily occurs in the locking process of PCBA and bottom shell in existing assembly lines, resulting in reduced production efficiency of the assembly line.

[0004] To achieve the above and other related objectives, this utility model provides a PCBA and bottom shell locking device, comprising:

[0005] frame;

[0006] A conveying mechanism is mounted on the frame and is used to transport a tray on which PCBA and a bottom shell are loaded.

[0007] At least two sets of transfer and locking mechanisms are distributed along the length of the frame and are located on one side of the conveying mechanism along the width. The transfer and locking mechanism includes a transfer module and a locking module. The locking module is used to lock the PCBA to the bottom shell, and the transfer module is used to drive the locking module to move.

[0008] The identification module includes an upper vision module and a lower vision module. The lower vision module is mounted on the rack and is used to identify the posture of the screw to be locked extracted by the locking module. The upper vision module is mounted on the transfer module and is used to identify the locking hole positions of the PCBA and the bottom shell.

[0009] Optionally, the frame is provided with a blocking and positioning component, which is used to block the material tray along the transmission direction of the conveying mechanism.

[0010] Optionally, the frame is provided with a lifting mechanism, which is used to lift and move the material tray on the conveying mechanism along the height direction of the frame, so that the material tray is disengaged from the conveying mechanism.

[0011] Optionally, the frame is provided with a height detection element for detecting the height of the tray.

[0012] Optionally, the frame is provided with a bracket, the bracket is provided with a baffle, and the baffle is provided with a through hole corresponding to the locking hole.

[0013] Optionally, the baffle is provided with a plurality of pressing parts, which are used to contact and press the PCBA.

[0014] Optionally, the bracket is provided with a guide post, the baffle is slidably connected to the guide post, and a limiting part is provided at one end of the guide post along the axial direction, the limiting part being used to limit the baffle along the height direction of the frame.

[0015] Optionally, the frame is provided with a hopper for storing screws.

[0016] Optionally, the transfer module is provided with a connecting arm, which includes a first arm and a second arm. The first arm is used to install the locking module, and the second arm is used to install the upper vision module.

[0017] Optionally, both the first arm and the second arm are provided with reinforcing ribs.

[0018] As described above, this utility model has the following beneficial effects: After the PCBA and the base shell are assembled, they flow into the fastening station. By distributing at least two sets of transfer fastening mechanisms along the length of the frame, the fastening of the PCBA and the base shell screws is divided into two parts. The two sets of transfer fastening mechanisms work together to complete the fastening operation of the PCBA and the base shell screws. The fastening time of each set of transfer fastening mechanisms for the PCBA and the base shell screws is less than the assembly time of the PCBA and the base shell. Therefore, after the PCBA and the base shell are assembled, they can flow smoothly into the fastening station, avoiding the assembled PCBA and the base shell from being stuck in the assembly station, thereby effectively improving production efficiency. By setting a lower vision module to identify the screw posture extracted by the fastening module, screws with misaligned postures can be screened and discarded, avoiding screws being fastened off-center on the PCBA, thereby avoiding product quality problems. By using an upper vision module to identify the fastening hole positions of the PCBA and the base shell, the fastening module can accurately fasten the screws to the fastening holes, improving fastening accuracy.

[0026] Before describing the embodiments of this utility model in detail, the application environment of this utility model will be described first. The technology of this utility model is mainly applied in the field of screw fastening equipment technology. This utility model is used to solve the problem that material blockage easily occurs in the fastening process between PCBA and bottom shell in existing assembly lines, resulting in reduced production efficiency of the assembly line.

[0027] Please combine Figures 1 to 3 As shown, this utility model provides a PCBA and bottom shell locking device.

[0028] In an exemplary embodiment of this application, the PCBA and bottom shell fastening device includes: a frame 1; a conveying mechanism 2, disposed on the frame 1, the conveying mechanism 2 being used to transport a tray 201 on which the PCBA and bottom shell are loaded; at least two sets of transfer fastening mechanisms 3, distributed along the length direction of the frame 1 and located on one side of the conveying mechanism 2 along the width direction, the transfer fastening mechanism 3 including a transfer module 301 and a fastening module 302, the fastening module 302 being used to fasten the PCBA and bottom shell, the transfer module 301 being used to drive the fastening module 302 to move; and an identification module 4, including an upper vision module 401 and a lower vision module 402, the lower vision module 402 being disposed on the frame 1, the lower vision module 402 being used to identify the posture of the screw to be fastened extracted by the fastening module 302; the upper vision module 401 being disposed on the transfer module 301, the upper vision module 401 being used to identify the fastening hole positions of the PCBA and bottom shell.

[0029] In this embodiment, after the PCBA and the base shell are assembled, they flow into the fastening station. At least two sets of transfer fastening mechanisms 3 are distributed along the length of the frame 1, dividing the PCBA and base shell screw fastening into two parts. The two sets of transfer fastening mechanisms 3 work together to complete the PCBA and base shell screw fastening operation. The fastening time of each set of transfer fastening mechanisms 3 is less than the assembly time of the PCBA and base shell. Therefore, after the PCBA and base shell are assembled, they can smoothly flow into the fastening station, avoiding the assembled PCBA and base shell from being stuck at the assembly station, thus effectively improving production efficiency. By setting a lower vision module 402 to identify the screw posture extracted by the fastening module 302, screws with misaligned postures can be screened and discarded, preventing screws from being fastened off-center on the PCBA, thereby avoiding product quality problems. By using an upper vision module to identify the fastening hole positions of the PCBA and base shell, the fastening module 302 can accurately fasten the screws to the fastening holes, improving fastening accuracy.

[0030] It is worth noting that the conveying mechanism 2 is a motor-driven chain conveyor, the transfer module 301 is a robotic arm module, the fastening module 302 is a self-locking screw machine, and the upper vision module 401 and the lower vision module 402 are both CCD cameras.

[0031] In an exemplary embodiment of this application, a blocking positioning component 5 is provided on the frame 1, which is used to block the material tray 201 along the transmission direction of the conveying mechanism 2.

[0032] In this embodiment, the blocking positioning component 5 is a blocking cylinder.

[0033] In an exemplary embodiment of this application, a lifting mechanism is provided on the frame 1. The lifting mechanism is used to lift and move the material tray 201 on the conveying mechanism 2 along the height direction of the frame 1, so that the material tray 201 is disengaged from the conveying mechanism 2.

[0034] In this embodiment, the lifting mechanism is a screw drive device driven by a motor. The lifting mechanism lifts the material tray 201 away from the conveying mechanism 2, thereby keeping the material tray 201 in the locking position and avoiding friction and vibration between the material tray 201 and the conveying mechanism 2.

[0035] In an exemplary embodiment of this application, a height detection element 6 is provided on the frame 1, which is used to detect the height of the tray 201.

[0036] In this embodiment, the height detection element 6 is a through-beam sensor. The height of the material tray 201 is detected by the height detection element 6, thereby controlling the lifting mechanism to drive the lifting height of the material tray 201.

[0037] In an exemplary embodiment of this application, the frame 1 is provided with a bracket 7, the bracket 7 is provided with a baffle 701, and the baffle 701 is provided with a through hole 701a corresponding to the locking hole.

[0038] In this embodiment, the baffle 701 is suspended above the conveying mechanism 2 by the bracket 7. By opening through holes 701a on the baffle 701 corresponding to the locking holes of the PCBA and the bottom shell for the locking module 302 to pass through, the locking module 302 can pass through the through holes 701a to align and lock the screws with the locking holes. By setting the baffle 701, the screws on the locking module 302 are effectively prevented from falling off and damaging the PCBA circuit board.

[0039] In an exemplary embodiment of this application, the baffle 701 is provided with a plurality of pressing parts 701b, which are used to contact and press the PCBA.

[0040] In this embodiment, the pressing part 701b is a columnar structure extending along the height direction of the frame 1 on the baffle 701. The pressing part 701b on the baffle 701 is positioned to correspond to the part of the PCBA where no electronic components are installed or the locking hole on the PCBA for locking with the top cover. This avoids damage to the electronic components on the PCBA caused by the pressing part 701b contacting and pressing with the PCBA. By setting the pressing part 701b to contact and press with the PCBA, a pre-tightening force is provided between the PCBA and the bottom shell. On the one hand, the hot glue between the PCBA and the bottom shell can be pressed evenly. On the other hand, the distance between the locking hole of the PCBA and the locking hole of the bottom shell can be shortened, thereby avoiding the risk of screw misalignment.

[0041] In an exemplary embodiment of this application, the bracket 7 is provided with a guide post 702, the baffle 701 is slidably connected to the guide post 702, and one end of the guide post 702 along the axial direction is provided with a limiting part 702a, which is used to limit the baffle 701 along the height direction of the frame 1.

[0042] In this embodiment, by sliding the baffle 701 on the guide post 702, when the height detection element 6 detects the signal of the material tray 201, the lifting mechanism stops. At this time, the material tray 201 is in contact with the pressing post. The baffle 701 is slidably connected to the guide post 702, thereby buffering the inertial force of the material tray 201 and reducing the rigid contact between the pressing post and the PCBA, thereby reducing the risk of impact damage between the PCBA and the pressing post. The limiting part 702a is a cylindrical structure with a diameter larger than that of the guide post 702, thereby preventing the baffle 701 from falling off the guide post 702 under the action of gravity.

[0043] In an exemplary embodiment of this application, the frame 1 is provided with a hopper 101 for storing screws.

[0044] In this embodiment, the transfer module 301 is used to drive the locking module 302 to extract the screw to be locked in the hopper 101, and to move the locking module 302 to the position of the tray 201. The locking module 302 locks the screw to be locked from the hopper 101 into the locking hole of the PCBA and the bottom shell, thereby realizing the locking of the PCBA and the bottom shell.

[0045] In an exemplary embodiment of this application, the transfer module 301 is provided with a connecting arm 8, which includes a first arm 801 and a second arm 802. The first arm 801 is used to install the locking module 302, and the second arm 802 is used to install the upper vision module 401.

[0046] In an exemplary embodiment of this application, both the first arm 801 and the second arm 802 are provided with reinforcing ribs 803.

[0047] In this embodiment, the first arm 801 is provided with two reinforcing ribs 803, and the second arm 802 is provided with one reinforcing rib 803. By providing reinforcing ribs 803 on the first arm 801 and the second arm 802, the structural strength of the first arm 801 and the second arm 802 is effectively improved. The reinforcing rib 803 is a triangular reinforcing rib 803.

[0048] Working principle: After the PCBA and base shell are assembled, they flow into the fastening station. At least two sets of transfer fastening mechanisms 3 are distributed along the length of the frame 1, dividing the PCBA and base shell screw fastening into two parts. The two sets of transfer fastening mechanisms 3 work together to complete the PCBA and base shell screw fastening operation. The fastening time of each set of transfer fastening mechanisms 3 is less than the assembly time of the PCBA and base shell. Therefore, after the PCBA and base shell are assembled, they can smoothly flow into the fastening station, avoiding the assembled PCBA and base shell from being stuck at the assembly station, thus effectively improving production efficiency. By setting a lower vision module 402 to identify the screw posture extracted by the fastening module 302, screws with misaligned postures can be screened and discarded, preventing screws from being fastened off-center on the PCBA, thereby avoiding product quality problems. By using an upper vision module to identify the fastening hole positions of the PCBA and base shell, the fastening module 302 can accurately fasten the screws to the fastening holes, improving fastening accuracy.

[0049] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
